Consumer advice
Look up the actual supplement facts panel (not shown in this listing) before buying - it should list mg amounts per ingredient. If it's a proprietary blend with only a total weight, assume the pricier ingredients (rhodiola, cordyceps) are underdosed relative to the cheap fillers. If you just want cordyceps or rhodiola, standalone extracts with labeled doses cost much less per serving.
Claims vs Evidence
